Kaftan hates every game lol
The reason you have to drudge back and fourth is because you are a space engineer, and it's your job to get the ship working again, but your survival now depends on it as well. I love the concept! You hate and want to escape from the ship because it's infested with horrible things, yet you have to fix and take care of the ship and defend it from asteroids, because if the ship goes down, you die with it.
The story of the ship is scattered in audio logs that YOU have to find and collect, there's some basic puzzles and I hear there's a twist on the characters of something (I'm only on chapter 5)
Overall it's an awesomely atmospheric game that sucks you in (it doesn't even have a HUD)
As for scares, the monsters get more and more grotesque and it got me to the point of being cautious and hesitating if I should enter that dark room or not. This game is what Doom 3 should have been.
